perhaps im missing something here, but if the limit is 4700, then there shouldn't be any issue towing at 4700, all day every day. that is in fact what its rated at, it should be able to be USED at that.
A 4 Runner can be used at the max limit nevada. However the concept you're responding too is not what CAN be done, but how often it should be. Orc addressed that very well in a previous post:
"When you play at the limit something is going to give sooner than if you were at around half."
Let me explain it with an analogy. A man is 6' 1" and a husky 200#. Can he carry 100% of his weight for a total of 400 pounds? Sure if he's in good physical condition and lifts carefully to protect his back.
However in your example this man would be carrying 100% of his body weight "all day every day," and that's quite a different thing altogether isn't it? The short version is while the 4 Runner is rated to carry 4,700#, Toyota built an SUV not a tractor trailer.
On your other post you make a fair point we don't have specifics on the weight Ryan1975 was towing. However it's not like we're in the dark here, and a reasonably accurate estimate is possible. For example I believe the blue Landcruiser being towed is a 60 series. With the big tires and wheels we're at about 5,000 pounds.
The 50s' Ford with the primer hood and front quarter panel was made when Detroit stamped out parts from a much heavier gauge steel than used today. Forget aluminum. She looks like a 1958 Victoria hardtop sedan which came off the line at a bare minimum of 3,500 pounds. I can also tell you from experience old cars like that "gain" weight through the years with all kinds of stuff put in and on them.
Then we have the newer Corvette which is obviously a C6 body, and if not an ounce was added or being carried inside, is still 3,300 pounds. Which brings us to the trailer.
The one Ryan tows with must be a good 18" feet at least. Look how much is left over with a 15 1/5 foot Landcruiser sitting on it. Possibly it's all aluminum trailer in the 1,200 pound range. However that's really unlikely since it would be one mother of an expensive trailer. This looks like a classic 18' steel trailer which come in at about 1,800 pounds.
So if the Corvette was dead empty that "Ooops" trip from New York to Michigan to KC was flying down the Interstate at about 5,100 pounds minimum. The Ford Victoria tow was in the range of 5,300 pounds, and the massive Landcruiser was moving at highway speeds while carrying along something in the neighborhood of 6,800 pounds !
If someone thinks TitanPat was harsh in his post while pointing out the safety hazard of doing this, fair enough. However his point these vehicles were being carried across several states in a manner that very well could have endangered the lives of other people on the road, is very real given the apparent facts.
